An object of my invention is to provide a detachable frame for the wheelof the side car which comprises in a single unit the wheel and its axle,wheel frame, two laminated springs, mudguard, stand and foot board, andsimple means for securely fixing such frame to the side car frame.Another object is to provide corresponding securing and interlockingdevices on thetubular T- joints forming part of the frames ofthe sidecar and the wheel. I attain these objects by the mechanismfullydescribed with reference to the drawings in which:

Figure 1 is a perspective view of a motorcycle with the side car and thewheel frame unit attached thereto; Fig. 2 is a perspective view of theide car and its frame or chassis; Fig. 3, a perspective view of thewheel frame unit with the wheel and axle removed therefrom; Figs. 4 and5, details of lugs a, a and b for attaching thewheel frame unit to theside car frame unit.

The side car frame or chassis A- for attachment to the bicycle is madeof. any suitable design or construction and is provided with lugs a, aand a tapped hole at a by which to attach the wheelframe B.

The wheel frame B, or framewhich carries the wheel axle and which may beof any known construction and arrangement of frame members, is fittedwith two laminated springs C longitudinally applied thereto with the;thick ends fast in the head piece B* of the frame B and with the eyes inGopies of this patent may be obtainedfor hangers B The frame is providedwith lugs or memers b by which it can be at tached to the car chassis. Q

The lugsor members a, a? on the side car chassis A are made withcrosswise ribs on the face and the lugs or members I) are made withcorresponding grooves or recesses, or vice versa, which whenboltedtogether take the *weight and longitudinal or propelling thrustrelieving the bolts 6 of shearing stresses.

The bolts 6 are preferably cast or brazed into the lugs b and passthroughthe lugs a, a and the bolt 6 passes-through the trans verse tubemember 0 of the footboard or step bracket and is screwed into the part aof the lower side tube of the chassis. The lugs a, a and b, are fast onthe sides of tubular T-.joints of both frames. The wheel frame B ismadewv-ith a footboardor step C preferably pivoted or hinged to enableit to be folded, with a stand D and mudguard brackets d, Z I he side carbody is denoted by E and the motorcycle by F.

I claim: a l, A Sidecar frame or chassis havingtubular T-joints, sideconnecting lugs fast on the tubular T-joints in combination with a wheelframe, having an angular head-piece and carrying spring hangers, a wheeland axle mounted in said wheel frame, two longitudinal laminated springsfast in said head-piece and secured in said hangers, mudguard, stand,and footboard on said wheel frame and antisshearing lugs at the side ofsame for engagement with those on the chassis.

2. In a sidecar, a chassis, tubular T- joints forsame, perforated lugsfast on the outer side of said joints, ribs on the face of the lugs, incombination with a wheelframe,

a wheeland axle in same, and lugs at the side of the wheel frame,crosswise grooves or recesses in the face and bolts fast in the centerof these lugs. p
